miss at all rpms

[steelzeus]

As the title states I have a miss at all rpms. When its warming up it will miss but when it gets down to idle speed its just fine, but everything above idle it will miss at a constant rate like vroom miss vroom miss vroom miss etc if that helps.

ok more info when I started it up today it held 2000 rpm during the warmup but as soon as it dropped down from that it started to miss like before

Change your spark plugs with some NGK BPR6ES's gapped at .028 and run a boost leak test, then report back with your results.

Its got new plugs in it Ill do a boost leak test tomorrow

What kind of plugs did you put in it? If they were platinums or iridiums pull them out immediately and throw them in the trash. DSM's do not respond well to the these styles of plugs, stick with the tried and true NGK coppers.

Definitely check for boost leaks and make sure all your vacuum lines are connected securely and do not have any cracks in them.

Check your plugs, plug wires, coilpack???

The plugs are bpr6es NGK gapped at .028. will I need a two inch coupler for a 13b turbo, for the boost leak tester.

the boost leak will tell you alot, and that may well be the problem. I had a similar problem recently and it turned out to be a faulty TPS sensor. you should defiantly test yours. The testing process isnt complicated and I'm sure you can find the instructions on how to if you search or if you have a manual. when you do test it be sure your car is warmed up first as a faulty one can sometimes check out ok if its still cold.

Good luck

i did a boost leak test and its leaking on the #2 injector and at the part where the throttle plate "pin" is I also did notice a clicking noise around the tps,cas area too almos like a short like a electrical buzz any ideas. Also is there any way to fix the throttle plate shaft is there an o-ring there or something?

You might also want to check your fuel filter. I had one clog up on me and it was a pain in the butt to diagnose.
